Hello,
You need to contact WooCommerce support with this question because it displays wrong information even with the default theme. It means that our theme is not the reason of the problem and we can do nothing from our side. We are able to help you only with issues related to XStore theme code https://themeforest.net/page/item_support_policy
In case you have a problem even with the default WP theme then you need to contact WooCommerce or WordPress support.
We hope for your understanding.
Regards
